IMPROVEMENT IN MACHINES FOR SPLITT'ING HOOP-POLES.

Specification forming part of Letters Patent No. 192,874, dated July 10,1877; application filed January 6, 1877.

CASE G.

To all whom it may concern Be'it known: that I, JAMES: A. PEOPLEs, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Splitting Hoop- Poles, of which the following is a specifica tion:

My invention relates to machines of the class in whichv hoop-poles are drawn` toward a splittingknife by rotating feed-rolls; and my improvements consist, first, in combining feed-rolls mounted in movableand self-adjusting bearings withy driving mechanism so arranged as tok operate with equal facility in any of the positions assumed by the feed-roll. shafts; second,`in combining two feed-rolls, each. movable independently in` its bearings, with devices for` maintaining the tension of both rolls upon the pole which passes be.- tween them, while admitting? of ther movement of each roll-shaft toward or from the other, third, in` combining twocylindrical feedrolls and a supplementary V-groovedor bevel-faced ring or rings, fourth, in combin ing a removable knife-support and centering apparatus,.and a stationary clampor' clamps upon the frame 5` fifth, iny combining twolpairs of dischargingrollsanddevicesfor admitting of independent movement.` of the.V bearings-of twoof the rolls, while maintaining equal tension upon. thesplintsf and nor-mal operation of the driving-gearing.

In the accompanying drawings, Figure l is a side view,` inv elevation,i of a machine for splitting hoop-poles, embodying" my irnprovements; Fig. 2, a plan or top view of the same;` Fig.-3, a vertical transverse sec-l tion of the` same at. the center of the feedroll` shafts; Fig. 4,a similar sectionf at the center of the. dischargingrollsg. Figs.A 5 and 6, similar. sections,Y on an' enlarged scale, at the center of the feedlrolls, showing the supplementary bevel-faced ringsintwopositions;

Figs. 7 and 8, detailedl views of a` portionfof the driving-gearingof thedischarging-rolls; l

`of the` upper feedshaft rest,` are concentric with the pinionl 121,6, and the slots bE of the Fig.' 9', a view of the; upper feedfrolkand one of the supplementary rings of the lower; and Fig. 10, a side view, in elevation, of one of the feed-roll housings.

The frame or table A of the machine has secured upon it, at or near one of its ends,

`two vertical housings,B,for the bearings-of Vin the upper portion of the housings B. The "lower feed-roll B3 is likewise cylindrical,but

without side anges, and is secured.` upon` a shaft,l B1, mounted in bearings b5, fitted to and movable` within slots bi1 in` the lower portion of the housings. The bearings b2 of the upper feed-roll are articulated byflinks b1 to a horizontal plate, bs, and the bearings b5 of the lower roll are similarly connectedfby links b11 to a lower 'horizontal p1ate,b9.V A spring,

` b10,.connects the plates. b1 and b9 in such-.man- `ner that its tension acts equally upon the bearings of the upper and the lower roll, and in opposition to4 their movement apart, so as to maintain constant and equal pressure of each of the` rolls upon the ,pole passing be- 1 tween them.` The 'rollsareldrivenlby al shaft,

B5, mounted in fixed bearings in thehousings B, and having a pu1leyBf", upon onefof its ends, carrying a belt, A2, from the pulley a? of thedrivingshaft A1. y

A. spur-pinion, 1218, on the shaftBf, adjacent to the pulley B6, mesheswith a `gear-1111, on

the lower feed-roll shaft; B4,V andra similar pinion,b13, on.l the opposite end-ot' the shaft B5 rotates a gear, b, on the upperfeed-roll shaft` Bthrough the intermediationV of` the pinions b11 b15 616, each of which` rotatesfrupon a stud or within abearing securedto theadjacent housing B.

The curved` slots b4in which= the bearings lower feed-shaft are concentric with the shaft B5, by which arrangement it will be obvious that the gears of the yfeed-shafts will mesh with the respective driving-pinions in any of the positions which the shafts may assume when separated by the passage of a pole of varying thickness between the feed-rolls.

The object of employing three intermediate pinions for drivingthe upper roll-shaft is to enable the centers of the upper and lower slots to be placed as nearly as practicable in the same vertical plane.

For the purpose of feeding angular splints two supplementary rings, B1 B8, each of which is beveled or inclined at the side of its periphery adjacent to the other,-are suspended upon pins B9, secured to the housings, and by elevating the upper shaft B2 may be slipped around the -lower feed-roll B3, so as to rest upon and rotate therewith, their beveled faces presenting an angular or V-shaped groove, which receives the angular portion ot' the splint. Instead of two bevel-faced rings, as shown, a single ring having a V-groove in its periphery might be employed for the same purpose.

The hoop-pole is fed by the rolls B1 B3 to the centering-rolls l, by which it is centered to the splitting-knife D. The centering-rolls and their attachments, and the knife, are fully described and shown in an application for Letters Patent filed by me simultaneously herewith, and designated Case B, and need not, therefore, be here specifically described.

The knife-support D1 and the frames I', in which the centering devices are mounted, are eachl fitted to dovetail grooves in a stationary clamp or clamps, J, secured to the top of the frame, so that either the knife or the centering apparatus, or both, can be readily removed and replaced whenever required.

The splints of the hoop-pole, after passing the knife D, are caused to diverge by a wedgeshaped divider, D2, which directs them to the upper and lower pairs of vdischarging-rolls U1 'C2 and U3 G4, which are respectively secured upon shafts c1 c2 and c3 c4, mounted in bear-V ings in the housings C. The bearings of the klower roll C2 of the upper pair,and of the upper roll O3 of the lower pair, are each tixed,

- but the bearings c5 of the roll G1 and the bearings cf of the roll G4 are fitted to vertical slots in the housings, within which they have a limited range of movement. The bearings c5 are connected, by bars or links c", to a horizontal plate, o9, and the bearings c6 are similarly connected, by links or bars c11,to a lower plate, o1", a spring, 011, being connected to the plates o9 c1, with a tendency to oppose their separation, similarly to the spring described in connection with the feed-rolls.

By this arrangement the tension of the spring is constantly exerted upon both pairs of rolls, and equally upon each pair.

The discharging-rolls are driven by a shaft, E, mounted in bearings in the housings G, and having secured upon one of its ends a pulley, E', carrying a belt, A3, from the pulley a? of the driving-shaft A1,- and on the other a spur-pinion, e, meshing with a similar pinion, e1, on the shaft c2. A pinion, e2, on the shaft c2 meshes with a pinion, e3, on the shaft o3. The shaft c3 carries upon its opposite end a pinion, e4, which meshes with a pinion, e5, and this, in turn, with a. pinion, e6, on the shaft c1. The pinion e5 rotates upon a stud, which is articulated by links c1 e8 to the shafts c1 c3, so as to remain in gear with the pinions e4 and c6, while admitting of vertical movement of the shaft c1. The shaft c4 is driven in a similar manner from the shaft c1, the latter shaft carrying a pinion, e9, which gears with a pinion, e1", rotating on a stud connected by links 612 613 with the shafts c2 c4, and gearing, in turn, with a pinion, 611, on' the shaft 04. l

I claim as my invention and desire to secure by Letters Patentl. The combination, in a machine for splitting hoop-poles, of an upper and a lower feedshaft, each driven by gearing, the bearings l for said shafts fitted to and movable within slots curved concentrically with their drivin g-gears, and a spring or springs connecting the bearings of the two shafts, substantially as set forth.

2. The combination, in a machine for splitting hoop-poles,of two feed-roll shafts, mounted in bearings fitted to and movable in curved slots, pivoted links articulating the bearings of the upper and lower shafts, with upper and lower plates, respectively, and a spring Efionnecting said plates, substantially as set orth.

3. The combination, in a machine for splitting hoop-poles, of a cylindrical feed-roll having side iianges, a cylindrical feed-roll without flanges, and a supplementary V-grooved or bevel-faced ring or rings, which can be adjusted upon or removed from said last-named roll-shaft, substantially as set forth.

4. The combination, in a machine for'splitting hoop-poles, of a knife-support and centering apparatus, having their bases fitting into dovetail grooves in a stationary.transverse clamp secured upon the frame, so that either or both may be readily removed therefrom, substantially as set forth.

5. The combination, in a machine for splitting hoop-poles, of two pairs of dischargingrolls and their shafts, one shaft of each pair being mounted in movable bearings, and a spring connected at its en'ds to two plates, respectively jointed to the movable bearings of the two shafts, so that the spring shall act with equal tension upon cachot' said' shafts, substantially as set forth.
